(13) ASME FOREWORD

The first edition of this Code was published inJanuary 1921. It was prepared by an American Societyof Mechanical Engineers (ASME) Committee onProtection of Industrial Workers with the assistance ofrepresentatives of a number of interests including manu-facturers, insurance carriers, regulatory bodies, andtechnical societies.

Subsequently, ASME requested the AmericanEngineering Standards Committee (AESC) to authorizethe organization of a Sectional Committee to undertakethis revision. They acted favorably on this request, andin January 1922, assigned sponsorship for the projectjointly to the American Institute of Architects, theNational Bureau of Standards, and ASME, all three ofwhom had taken an active part in the preparation ofthe first edition of the Code.

The organization meeting of the Sectional CommitteeA17 was held in November 1922. A number of meetingsof the Committee were held during the next two yearsand in July 1925, a revision of the 1921 Code was com-pleted, approved by the AESC, and published as anAmerican Standard.

Subsequent to the publication of the 1925 revision ofthe Code, the necessity for development research on thedesign and construction of car safeties and oil buffersand for the development of test specifications for variousparts of elevator equipment was realized.

As a result, a Subcommittee on Research,Recommendations, and Interpretations was appointedin 1926. This subcommittee held regular meetings there-after until interrupted by the war in 1940, and carriedon an extensive test program at the National Bureau ofStandards in connection with oil buffers and car safeties.Subsequent to the war, the name of this subcommitteewas changed to “Executive Committee for the ElevatorSafety Code.”

The information gained as a result of these tests,together with the developments that had occurred inthe design of the equipment as a result of installationsmade in very tall buildings, prompted the SectionalCommittee to prepare and issue the third edition of theCode in 1931. The third edition was approved by theSectional Committee in February 1931, and subse-quently by the sponsors and by the American StandardsAssociation (formerly the AESC) in July 1931.

Further experience and developments in the designof elevator equipment, led the Sectional Committee, inline with its policy of revising the Code periodically, toprepare the fourth edition in 1937, which was approved

viii

by the sponsors and by the American StandardsAssociation (ASA) in July 1937.

A fifth edition of the Code was well under way in1940 when it was necessary to suspend the work dueto the Second World War. However, a number of therevisions already agreed upon by the SectionalCommittee and approved by the sponsors and by theASA in April 1942, were issued as a supplement to the1937 edition. They were subsequently incorporated ina reprint of the 1937 edition in 1945. In response to publicdemand, requirements for private residence elevatorswere also issued in a separate supplement,ASA A17.1.5-1953, and incorporated into the Code asPart V in the 1955 edition.

The Sectional Committee reinitiated consideration ofthe fifth edition of the Code in 1946. Due to the consider-able period which had elapsed since the fourth revisionin 1937, and to the very extensive developments in theelevator art, the committee decided that the Code shouldbe completely rewritten and brought up to date.

Special subcommittees were appointed to prepare therevisions of the various requirements. The membershipof each subcommittee consisted of persons especiallyfamiliar with the requirements to be covered by thatsubcommittee. Fifteen subcommittees were set up witha total membership of over 150 persons. The member-ship of these subcommittees was not confined to mem-bers of the Sectional Committee. It also included otherpersons having expert knowledge of the subjects underconsideration by the subcommittees. These subcommit-tees and their personnel were listed in the 1955 editionof the Code.

The drafts prepared by these subcommittees werewidely circulated to interested groups for comment.After review of the comments and correlation of thedrafts, the fifth edition of the Code was approved bythe Sectional Committee, subsequently by the sponsors,and by the ASA in June 1955.

In December 1957, a Supplement to the Code listinga number of revisions was approved by the ASA andpublished by ASME.

A sixth edition was published in 1960 which incorpo-rated the revisions contained in the 1957 Supplement aswell as approximately 96 revisions which were approvedby the Sectional Committee in March 1960.

In 1958 the scope of the A17 Code was enlarged toinclude moving walks. The membership of the SectionalCommittee was expanded to include manufacturerswhose primary interest in the Committee was the devel-opment of rules and regulations on moving walks. A


c

subcommittee prepared a Safety Code for Moving Walkswhich was approved by the Sectional Committee, thesponsors, and by the ASA on March 20, 1962. This Codewas published as Part XIII of the A17.1 Code, and wasdesignated ASA A17.1.13-1962.

During 1962 and 1963, 38 additional changes to Parts Ithrough XII of A17.1 were approved by the SectionalCommittee, the sponsors, and the ASA, and were pub-lished as the 1963 Supplement to the 1960 edition of theCode.

A seventh edition was published in 1965 which incor-porated the rules of the Safety Code for Moving Walks,ASA A17.1.13-1962, as Part XIII, the revisions coveredby the 1963 Supplement as well as approximately 90other revisions approved by the Sectional Committee,the sponsors, and the ASA. The title of the Code wasalso changed to the American Standard Safety Code forElevators, Dumbwaiters, Escalators, and Moving Walks.

On August 24, 1966, the American StandardsAssociation was reconstituted as the United States ofAmerica Standards Institute. The designation of stan-dards approved as American Standards was changedto USA Standards. There was no change in the indexidentification or the technical content of the standards.At the same time, the ASA Sectional Committee, A17on A Safety Code for Elevators, was changed to theUSA Standards Committee, A17 on A Safety Code forElevators. Four supplements to this edition were pub-lished from 1967 through 1970.

The United States of America Standards Institute laterchanged its name to American National StandardsInstitute, Incorporated (ANSI) on October 6, 1969. Atthe time that the new name became effective, the desig-nation USA Standard was changed to AmericanNational Standard and the name of committees changedfrom USA Standards Committees to American NationalStandards Committees. The alphabetical designation ofstandard documents was changed from USA to ANSI.

The eighth edition of the Code (1971) incorporatedthe revisions covered by the four supplements and anadditional 94 revisions. Seven supplements were issuedfrom 1972 through 1976. Part XIV covering Material Liftsand Dumbwaiters with Automatic Transfer Devices wasadded in supplement ANSI A17.1d-1975.

The ninth edition of the Code (1978) incorporated 75revisions in addition to those covered by the previoussupplements. Part XV covering Special PurposePersonnel Elevators was added and the Reference Codes,Standards, and Specifications were moved from thePreface to a new Part XVI. Two supplements to thisedition were issued in 1979 and 1980.

The tenth edition of the Code (1981) incorporated therevisions covered by Supplements ANSI A17.1a-1979and ANSI A17.1b-1980, as well as the following newmaterial: Part XVII, Inclined Elevators; Appendix F,Seismic Regulations; and Appendix G, Recommended

ix

Practice for Accelerating Moving Walks. Rule 211.3 andPart V were also completely revised, with the PrivateResidence Inclined Lifts moved to Part XVIII. Numerousother revisions and additions were also included whichwere approved since the time of the 1980 supplement.

The tenth edition of the Code was approved by theA17 Standards Committee. Since that time, the commit-tee was reorganized in accordance with the ANSIAccredited Organization Method under the sponsorshipof ASME. With this reorganization, the National Bureauof Standards and the American Institute of Architectsrelinquished their roles as cosecretariats. The Standards,Conference, and Executive Committees were alsorestructured as the Main Committee and the NationalInterest Review Committee, with the WorkingCommittees (subcommittees) continuing to operate asbefore.

This reorganization also prompted a change in thetitle of the Code to the ANSI/ASME A17.1 Safety Codefor Elevators and Escalators. The title was also shortenedfor convenience, and it should not be construed that theCode no longer covers dumbwaiters, moving walks, orthe other equipment included within the Scope of theCode.

Two supplements to the 1981 edition were issued:ANSI/ASME A17.1a-1982 and ANSI/ASMEA17.1b-1983. The 1982 supplement included a new PartXIX covering Elevators Used for Construction. In the1983 supplement, the requirements for Private ResidenceInclined Lifts in Part XVIII were expanded and incorpo-rated into a new Part XXI covering Private ResidenceInclined Stairway Chairlifts and Inclined and VerticalWheelchair Lifts. Part XX was added to cover these samedevices installed in buildings other than private resi-dences. Requirements for Screw Column Elevators werealso added and designated as Part XVIII.

The eleventh edition of the Code (1984) incorporatedthe changes made in the 1982 and 1983 supplements, aswell as additional revisions.

The eleventh edition was updated with five supple-ments which were issued approximately every 6 monthsin 1985 through the spring of 1987. Appendix I (sinceredesignated as Appendix E) was added inANSI/ASME A17.1a-1985. Requirements for rack andpinion elevators were added in ANSI/ASMEA17.1c-1986, designated as Part XVI. The previous PartXVI (Reference Codes, Standards, and Specifications)was moved to Section 4 of the Introduction. InANSI/ASME A17.1d-1986, the requirements for side-walk elevators in Part IV, and alterations in Part XII,were completely revised.

The twelfth edition of the Code incorporated thechanges made in supplements A17.1a-1985 throughA17.1e-1987, as well as additional revisions. Amongthese changes was a complete revision of the require-ments for dumbwaiters in Part VII. The format of the


c

Code was also changed editorially to incorporateExceptions into the body of the Rules.

The thirteenth edition of the Code incorporated thechanges made in A17.1a-1988 and A17.1b-1989 as wellas additional revisions. Part XXII, Shipboard Elevators,was added in A17.1b-1989. Part XXIII, Rooftop Elevators,appeared for the first time in this edition.

The fourteenth edition of the Code incorporates thechanges made in A17.1a-1991 and A17.1b-1992 as wellas the revisions shown in the Summary of Changes.Safety requirements for seismic risk zone 3 and greaterwere moved from Appendix F into new Part XXIV,Elevator Safety Requirements for Seismic Risk Zone 2or Greater. Requirements for seismic risk zone 2 wereadded to Part XXIV.

The fifteenth edition of the Code incorporates thechanges made in A17.1a-1994 and A17.1b-1995 as wellas the revisions shown in the Summary of Changes.Part XXV, Limited Use/Limited Application Elevators,was added in A17.1b-1995. The rules in Part III have beenharmonized with the CAN/CSA B44, Elevator SafetyStandard, Sections 4 and 11, and Appendix G4.

The sixteenth edition of the Code incorporateschanges made in A17.1a-1997 through A17.1d-2000.Requirements for Mine Elevators have also been addedin Section 5.9 of this edition. In addition, the entire Codewas reformatted to incorporate a decimal numberingsystem. For this edition of the Code cross-referencetables have been provided in order to facilitate the corre-lation between requirements from the fifteenth editionof the Code to the renumbered requirements of the six-teenth edition and vice versa. It is also noted, that thisedition of A17.1 was the result of a joint effort betweenthe ASME A17 Elevator and Escalator Committee andthe CSA B44 Technical Committee to harmonize require-ments between the ASME A17.1, Safety Code forElevators and Escalators, and the CSA B44, Safety Codefor Elevators.

The seventeenth edition of the Code incorporateschanges made in A17.1a-2002 and A17.1b-2003. Addi-tionally, in Sections 8.10 and 8.11, cross-references havebeen updated to reflect ASME A17.2-2001, Guide forInspection of Elevators, Escalators, and Moving Walks.

The eighteenth edition of the Code is a fullybi-national standard. All former deviations between theASME A17.1 Code and the CSA B44 Code have beenfully addressed within this one Code. Additionally, thisedition incorporates revisions to address the advance-ment of technologies used in the design and constructionof elevator equipment which has enabled the installationof the equipment in other than traditional locations suchas machine rooms. New requirements have also been

x

added to address programmable electronic systems insafety-related applications of elevators.

The nineteenth edition of the Code incorporateschanges made in A17.1a-2008 and A17.1b-2009. Majorchanges include former periodic inspections now beingcovered under maintenance requirements. New require-ments have been added to address the means and mem-bers of suspension, compensation, and governorsystems for elevators. These new requirements are cov-ered in detail through reference to ASME A17.6, whichincludes the material properties, design, testing, inspec-tion, and replacement criteria for these means. Itincludes the requirements for steel wire rope, aramidfiber rope, and noncircular elastomeric-coated steel sus-pension members and provides direction for future con-structions as new technology develops.

This twentieth edition of the Code contains well overone hundred revisions made to existing requirements,as well as some new requirements being added, sincethe publication of the nineteenth edition.

New requirements have been added to address newtypes of elevator equipment being used in the industry,specifically wind turbine elevators and outside emer-gency elevators. In addition, requirements have beenadded to address a new feature called ElevatorEvacuation Operation (EEO) which allows for the useof elevators for occupant evacuation.

Besides the above, several major changes include thefollowing:

(a) An extensive update to the seismic requirementsof the Code that have been revised to include seismicforce levels as specified in the latest building codes inthe US (IBC) and Canada (NBCC). In order to facilitateincorporation of these requirements, a Guide for ElevatorSeismic Design has been separately published.

(b) Requirements have been updated related to themaintenance control program in order to improve clarityand organization for records, content, availability, andformat.

(c) Regarding qualifications for elevator inspectors(QEI), effective January 1, 2014, accreditation of organi-zations that certify elevator inspectors and inspectionsupervisors is being discontinued by The AmericanSociety of Mechanical Engineers. Requirements havebeen revised in this area to allow for accreditation to bedone by other organizations.

The following is a complete list of past editions andsupplements to the Code that have been published andthe dates when they received final approval. The dates ofissuance are also included for the documents publishedsince 1974, and the dates on which they became effectiveare included for those published since 1978.

ASME PREFACE

GENERAL

This Code is one of the numerous codes and standardsdeveloped and published by The American Society ofMechanical Engineers (ASME) under the general aus-pices of the American National Standards Institute, Inc.(ANSI).

The Code is intended to serve as the basis for thedesign construction, installation, operation, testing,inspection, maintenance, alteration, and repair of eleva-tors, dumbwaiters, escalators, moving walks, and mate-rial lifts.

Safety codes and standards are intended to enhancepublic health and safety. Revisions result from commit-tee consideration of factors such as technologicaladvances, new data, and changing environmental andindustry needs. Revisions do not imply that previouseditions were inadequate.

This Code applies to new installations only, exceptPart 1, and 5.10, 8.1, 8.6, 8.7, 8.8, 8.9, 8.10, and 8.11,which apply to both new and existing installations. Also,see ASME A17.3, Safety Code for Existing Elevators andEscalators, for further requirements.

The following conditions are not addressed in thisCode:

(a) assignment of the responsibility for compliance toany particular party.

(b) establishment of a frequency for periodic inspec-tions and tests. See Nonmandatory Appendix N for rec-ommended inspections and test intervals.

(c) assignment of responsibility for persons author-ized to make and witness inspections and tests.

APPLICATION OF REQUIREMENTS TO NEWTECHNOLOGY

With the advent of new technologies, materials, andprocesses in the mechanical, structural, electronic, andoptic fields, and the analytical capabilities now available,the need for flexibility to introduce products into themarketplace using these technical developments isdesirable. Previous editions of ASME A17.1 had long-standing provisions, in Section 1.2, that suggested thatAuthorities Having Jurisdiction should recognize safetyequivalent to that required by the Codes. This editionof ASME A17.1/CSA B44 recognizes ASME A17.7/CSA B44.7 provides a structured method for establishingthe safety of designs and products and that compliancewith ASME A17.7/CSA B44.7 is equivalent to compli-ance with the requirements in ASME A17.1/CSA B44.

FORM AND ARRANGEMENT

This Code consists of parts and sections, each coveringa specific subject so as to facilitate reference to therequirements.

The Foreword, Preface, Notes, and Appendices thatare included in this document, and the Interpretationsthat are provided as a separate booklet are not part ofthis American National Standard. They are advisory innature and are intended for clarification only.

In this edition, the revisions that are appearing for thefirst time are identified by (13). Where editorial changeshave been made, they are identified by (ED). See alsoSummary of Changes.

METRIC (SI) UNITS

This edition of the Code uses hard metric (SI) unitswherever practical. The acceptable equivalent imperialunits are shown in parentheses. Information on theusage of SI units and conversion to imperial units iscontained in IEEE/ASTM SI 10-1997 Standard for theUse of the International System of Units (SI): TheModern Metric System, ASME Guide SI-1, Orientationand Guide for Use of SI (Metric) Units, or CAN/CSA-Z234.1, Canadian Metric Practice Guide.

Tables related to speed and load use the hard metricand hard imperial units in common practice, eventhough they are not exactly equivalent (e.g., see Table2.22.4.1, Minimum Buffer Strokes). The tabular valueshave been derived using 8.2.1 formulas and the metricand imperial values for buffer strokes, safety stoppingdistances, etc., are therefore not equivalent.

(13) CSA PREFACE

This is the third edition of ASME A17.1/CSA B44, Safety Code for Elevators and Escalators. Itreplaces the previous edition of ASME A17.1/CSA B44, published in 2010, and the previouseditions of CSA B44, published in 2007, 2004, 2000, 1994, 1990, 1985, 1975, 1971, 1966, 1960, and 1938.

This Code is the result of a joint effort by the CSA B44 Technical Committee on the Elevator SafetyCode and the ASME A17 Committee on Elevators and Escalators to harmonize the provisions ofCSA B44 and ASME A17.1. This edition of ASME A17.1/CSA B44 consists of the completeASME A17.1 Code, with additional requirements applicable only in Canadian jurisdictions. TheseCanadian requirements are prefaced in the body of the Code by the following: “In jurisdictionsenforcing the NBCC. . .”

CSA B44 was originally developed to facilitate the implementation of uniform legislation acrossCanada and to replace the existing legislation, which had proved inadequate for prevailingelevator practices. The primary purpose of the Code is to establish minimum requirements,suitable for adoption by regulatory authorities throughout Canada, for the design, installation,and maintenance of elevators, escalators, dumbwaiters, moving walks, and material lifts. It isalso intended as a standard reference for architects, consulting engineers, elevator manufacturers,and building owners.

This Code was prepared for use in Canada by the CSA Technical Committee on the ElevatorSafety Code under the jurisdiction of the CSA Strategic Steering Committee on MechanicalIndustrial Equipment Safety. It has been formally approved by the CSA Technical Committee.

NOTES:(1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that

it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.(3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code

of good practice for standardization as “substantial agreement. Consensus implies much more than a simplemajority, but not necessarily unanimity.” It is consistent with this definition that a member may be includedin the Technical Committee list and yet not be in full agreement with all clauses of this Standard.
